It must be obvious, that this system is calculated to ensure a sound, 

 vigorous, and anuually improving breed.'* , ,, , 



When the worms are laid upon the papers, they sliould be given 

 some young leaves, covering the spaces between the twigs with them, 

 that, by degrees, the whole surface may be equally spread with silk- 

 worms. In case they should get into heaps, a leaf might be put over 

 them, to which they will adhere; and, being gently lifted, it may be . 

 put in any spot where the worms lie thinner. 



Whenever silkworms are added upon the paper where some worms 

 have already been deposited, they should have food given them ; i)ut 

 the worms that were first on the paper should not be again fed until 

 the other sheets of paper have been filled , Thus a fair number oi the 

 first worms will receive the second meal at one time. 



The worms take at least two days to come forth; consequently, the 

 first hatched will be larger than those that appear the second and third 

 days We have stated above, that the thermometer proves, that a room 

 can never be heated to a degree exactly equal in every point of space. 

 There will exist the difi'erence of a degree, and even more. By put- 

 ting the early worms in the coolest part of the room, and the late 

 hatched worms in the hottest, and by feeding the latter rather higher, 

 it is practicable to bring them nearly to an equality. 



It has been said, that, if the worms which appear the first day are 

 in very small quantity, as it mostly happens, it is of no consequence, 

 because the main portion comes forth the second and third days. How- 

 ever, if it is required that those first hatched should be reared, they 

 ought to be put in an angle of the sheet of paper belonging to the num- 

 ber of their box, and only be allowed half the quantity of food which 

 is given to those later worms, on the first and second day. 



In general, the silkworms come forth more abundantly in the fore- 

 noon, when the sun shines warmly into the room; the room being then 

 hotter than at night. The great alterations to which the eggs are ex- 

 posed, occur in the night: if those who have the care of the silkworms 

 at night, heap up the fire, that they may take their rest without having 

 to make it up, the augmentation of heat affects, and even spoils the 



embryo. , , , . . . 



It has been observed, that, some days, the hatching of the worms 

 was most abundant in some boxes, and equally so m all the hours of the 

 day as in the morning. . . 



Where worms are fed on shares, an easy and beneficial improvement 

 would be, that all the eggs be hatched in boxescapable of holding twen- 

 ty or thirty ounces, constructed in the proportions before-mentioned, 

 and that as fast as the worms come forth, the sheets of paper should b©

 important to direct the attention of the readerto the different iM-actice of the experi- 

 enced cultivator referredto above. If the direction of Dandolo.to throw away the worms 

 ofthe first and fourth days' hatching, be not adopted, we sl.ould never omit to keep 

 the productions of those days separate from the others liatched un the two hrst davs, 

 in order that each parcel may be brought forward as equal as possible, and that all the
